Title: Improved bis(beta-hydroxyethyl) terephthalate
IPC: C07C69/82
Filed: 1954-10-28
Abstract: Bis - (beta - hydroxyethyl) - terephthalate obtained from terephthalic acid made by the nitric acid oxidation of a substituted aromatic compound is purified by treating an aqueous solution thereof with sodium hyposulphite and isolating the bis - (beta - hydroxyethyl) - terephthalate from the solution. The process is preferably carried out at or near pH7, and it is usually necessary to add an alkaline substance to the aqueous soultion of the bis-(beta-hydroxyethyl) - terephthalate, e.g. hydroxides, carbonates, bicarbonates, salts of weak acids and preferably a sparingly soluble carbonate, e.g. calcium carbonate. The amount of sodium hyposulphite required may be determined by using aqueous methylene blue as an external indicator. In examples: bis-(beta-hydroxyethyl)-terephthalate in aqueous solution is treated with sodium hyposulphate after addition of calcium carbonate (1) and after addition of ammonium hydroxide (2) after a similar treatment in (1) the aqueous solution is treated with decolorizing charcoal (3). Specification 623,669 is referred to.

Title: Hydraulic mooring winch
IPC: B66D1/08
Filed: 1961-12-23
Abstract: A mooring winch comprises an hydraulic transmission including a pump 10, 11 in circuit with hydraulic motors 23 . . . 26 for operating the winch drum, a hand-controlled valve 22 for regulating the quantity of fluid fed to the motor by adjusting a fluid by-pass, and another bypass valve 32 in parallel with the motor and responsive to the pressure difference between inlet and outlet pipes 29, 30 of the motor to maintain the pressure difference constant, an adjusting device 52 . . . 57 varying the pressure difference and accordingly adjusting the tension in the mooring line. The pump comprises two radial-vane units 10, 11 in parallel, a safety valve 14 protecting the unit 10 and a one-way valve 16 passing fluid from the pump 11 to a common main pipe 18. The valve 22 is the same as the valve shown in Fig. I of Specification 777,230 (see Group XXIX). The motors comprise a three-chamber radial vane motor 23 . . . 25 and a radial vane motor 26. The bypass valve 32 is adjusted by a pin 52 connected to a lever 53 pivoted at 54 and having an upper cam surface engaged by a roller 56 mounted in a controller 57 slidable leftwards of Fig. 5 along guides 58 to increase the pressure acting on the pin, and hence the pressure difference at which the by-pass valve opens, and correspondingly to increase the tension in the mooring line. The controller 57 coacts with indicating marks along the guides 58. A bracket 59 on the lever 53 abuts with a pin 60 fast on a shaft 61 turned by a handle 62, links &c. 63 connecting the handle to a valve 33. For adjustable control of the by-pass valve 32, the handle 62 is turned to a first position where it is interlocked with the handle controlling the valve 22, the pin 60 disengaging from the bracket 59 and the link 53. The valve 33 then passes fluid in the motor outlet pipe 30 to pressure-operated valves 27, 28, similar to those described in Specification 887,194 (see Group XXIX), which are thereby opened to admit pressure fluid to circuits 25, 26 of the motor, and simultaneously to a pressure-operated valve 15 which opens to bypass the pump unit 11. Accordingly, the pump unit 10 alone supplies all four motor circuits 23 . . . 26 and automatic regulation of the motor circuit is obtained through the by-pass valve 32, as determined by the setting of the controller 57. In a second position of the handle 62, the pin 60 engages the bracket 59 and draws the pin 52 downwards so firmly that the by-pass valve 32 is held closed at all normal working pressures. At the same time the valve 33 is conditioned so to control the pressure actuator valves 15, 27, 28 that the pump unit 11 is brought into circuit, and the motor circuits 25, 26 are disconnected. The winch can then be used for cargo lifting &c. under the control of the hand-operated valve 22. The motor circuits 23, 24, 25 are constituted by separate chambers in one radial-vane motor, and the motor circuit 26 by a separate motor at the opposite end of the winch drum. Two or more winches can be driven from the same pump.

Title: Thermal power plants
IPC: H02K44/08
Filed: 1965-07-06
Abstract: A thermal power plant includes a magnetohydrodynamio generator whose exhaust gases supply heat to a second thermal power plant, wherein the magnet coils of the generator are cooled, directly or through a secondary fluid, by liquefied natural gas which forms the fuel supply to the generator combustion chamber. The natural gas may also be used as fuel for the boiler of the second thermal power plant. A cryogenic secondary fluid may be used and the magnet coil may be cooled to superconductive temperatures. In the systems described, air is initially freeze dried and cooled by the liquified natural gas before passing to a separator from where the separated oxygen passes through a heat exchanger in the separator to the combustion chamber of the generator. The separated nitrogen is compressed and cooled by the natural gas and liquefied, the liquid being passed through the coils of the generator and the vapour produced returned to the separator to complete the closed cycle. The liquid natural gas is vaporized in the heat exchangers and passed as the fuel supply to the generator combustion chamber. In a modification the nitrogen vapour from the liquefier is used in a pro-cooler for air which has both been freeze dried and had the carbon dioxide removed, and the oxygen from the separator passes through a separate heat exchanger to cool the incoming air to the separator. In both embodiments the oxygen from the separator is used to freeze dry the incoming air as described in Specification 1,118,042. Reference has been directed by the Comptroller to Specification, 974,951.
Patent ES-319815-A1 (ES)
Title: Cigarette lighters
IPC: F23Q2/48
Filed: 1965-11-20
Abstract: A cigarette lighter flint feeding mechanism comprises a cylinder formed by upper and lower parts 13, 12 closed at its lower end containing an annular piston 19 which slides around a sleeve 16 containing a second piston 22, the sleeve 16 being fixed at its top end to the upper part 13 of the cylinder but being free at its bottom end. The volume below the two pistons is filled with a light oil and a compression spring 25 within the cylinder above the piston 19 causes the oil to exist under pressure which forces piston 22 upwards in sleeve 16 and holds a flint 24 in contact with an abrasive element 10 of the lighter through the top of the cylinder. The, areas of the pistons 19 and 22 in contact with the oil are in the ratio of 6: 1 and the sliding surfaces of the pistons are formed to retain sealing O-rings 20, 21 and 23. The flint feeding mechanism is mounted in a tubular housing 4 extending through the lighter fuel reservoir 7 and is screwed to the lighter by means of a threaded nose 30 of the cylinder. A fingerpiece 29 is mounted on the bottom of the cylinder. In a second embodiment, Fig. 3 (not shown), a cylinder 33 contains an inner flint supporting sleeve 34 closed at its lower end and formed at its upper end with an annular piston 36 which surrounds flint 35 and slides within the cylinder 33. The upward movement of the sleeve 34 is limited by an end closure cap 40 screwed to the cylinder 33, and removal of this cap will withdraw the sleeve 34 from cylinder 33. Air trapped above the piston 36 is compressed by the action of a compression spring 42 on the piston, the spring being held between the underside of the piston and the top of the cap 40. The pressure of the air acts on the underside of the flint 35 to force it against an abrasive element 10. Sealing 0-rings 44 are mounted in the neck 43 of the cylinder 33 through which the flint passes. In another embodiment, not shown, a flint tube is in communication at its lower end with a rubber balloon containing a pressurized fluid which forces a flint against a flint wheel.

Title: Method and apparatus for the continuous ringless spinning of yarn from separated staple fibers in a rotating spinning chamber
IPC: D01H4/10
Filed: 1967-02-25
Abstract: In a method of break-spinning using a rotary spinning-chamber having a collecting surface for the separated fibres and a withdrawing channel, the yarn passes over a rotary surface in its path between the collecting surface and the withdrawing channel, so that it is deflected and subjected to friction. The chamber 1 is arranged to be driven inside a stationary housing by a wharve 7. The cover 9 of the housing also closes the chamber, and has an inlet 10 for fibres separated at 12, and a channel 15 through which yarn is withdrawn by rollers 16. The side wall of the chamber is inclined and acts to guide fibres delivered at 10 to a collecting-surface 14 which is formed between the wall and the inclined surface 201 of a rim 20 concentric with the base of the chamber. The rim 20 projects upwardly above the direct line between the collecting surface and the yarn outlet so that the yarn is deflected and is entrained by and subjected to friction on the surface 201. This prevents a change in the direction of movement in the point when the yarn picks up the fibres, due to impurities or accumulations of fibres. Forms are described in which the rim has a flat upper surface, Fig. 4 not shown, and in which the fibres enter the chamber at the end opposite that through which it is withdrawn.
